Getting an error that "the following microblocks are not installed", clearly I've not found the right pack version yet, lol
Edit: For future people the version atm (19/03/2014) is: 1.0.9.
When you select monster in the ftb launcher, before clicking "Launch", underneath the "Maps" tab and between the "Download server and "Private packs" buttons is a combo box.
The combobox will likely say "Recommended". Click it and select 1.0.9 (or later if you are viewing this post much after 19/03/2014)
After 1.0.9 is selected just click Launch as normal.
Happy Gaming
Hope that proves to be useful to any new members that happen to drop by
